CANNON FALLS — Authorities are cracking down on people jumping off a 50-foot cliff into Lake Byllesby in southeastern Minnesota.

Goodhue County Sheriff’s Chief Deputy Kris Johnson said social media is driving growing popularity in jumping off the dangerous cliff. Sgt. Scott Powers said 73 people have been fined for trespassing so far this year on the site owned by the Boy Scouts of America.

Powers said the number of fines is down from a couple years ago due to tougher enforcement, but he says the focus is draining patrol efforts by the sheriff’s office.

According to a press release, Northern Star Council Executive Director John Andrews said that the Boy Scouts are happy about the enforcement. He said they dealt with the problem 15 to 20 years ago, and just learned recently it had arisen again.
